_____Most of this is %26quot;look up%26quot;. Few folks answer more than a couple of Qs and those are almost always computational. So here're two:
10. Arrange in order by volume milliliter, centiliter, micro liter, milliliter, liter?
1/1 Unit%26gt; 1/100 Unit %26gt; 1/1000 Unit %26gt; 1/1000000 Unit
12. Volume occupied by 16.4g of mercury?
vol Hg = mass Hg in g / density of Hg in g/cm^3 = 16.4g / 13.534 grams/cm^3 = 1.21cm^3 (3 sig digits)
